Group

The Mobile Security Group was es­ta­blis­hed in 2014 at the Fa­cul­ty of Elec­tri­cal En­gi­nee­ring and In­for­ma­ti­on Tech­no­lo­gy and is part of the Horst-Görtz-In­sti­tu­te for IT-Se­cu­ri­ty (HGI). The group is headed by Prof. Dr. Markus Dürmuth.

Our project Usability of Risk-based Implicit Authentication will receive funding through the North Rhine-Westphalian Graduate School “Human Centered Systems Security” (NERD NRW). The project studies the security and usability of so-called risk-based authentication, an additional layer that improves the security and usability of “traditional” password-based authentication. Also involved in the project is the Data & Application Security Group at TH Cologne.

We are looking for a highly qualified and motivated PhD student to work on the project. If you are interested please contact Prof. Dr. Dürmuth.

OMEN is a Markov model-based password guesser written in C. It generates password candidates according to their occurrence probabilities, i.e., it outputs most likely passwords first. If you are interested in the details on how OMEN improves on existing Markov model-based password guessing approaches, please refer to OMEN: Faster Password Guessing Using an Ordered Markov Enumerator.
